CARDIAC arrest may occur unexpectedly during various diagnostic and therapeutic procedures, particularly under anesthesia. Though infrequent (1 in every 500 to 5000 operations 1,2), each accident is a ...

Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

Junctional rhythm is an irregular heart rhythm that stems from a natural pacemaker in the heart known as the atrioventricular junction. The heart has several built-in pacemakers that help control its ...

The cardiac pacemaker harmlessly dissolves over the course of 35 days. (Courtesy: Northwestern University) Temporary cardiac pacemakers provide essential pacing for patients with short-term heart ...

Technically, the diagnosis of an anterior myocardial infarction on an ECG has never been validated in the setting of a paced rhythm, however that was the case in this ECG. There was acute occlusion of ...

The FollowPace study provides detailed documentation of current standard pacemaker care in a large representative sample of western pacemaker clinics. The results can therefore be considered a new ...

The rhythm is regular at a rate of 120 beats/min. A pacemaker stimulus occurs before each QRS complex (→). This is ventricular pacing. Because the pacing rate is 120 beats/min, the mode of pacing must ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can become a race against time to restore balance. For decades, doctors have ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...
